16 With meekness This is a most necessary admonition; for unless our minds are endued with meekness, contentions will immediately break forth. And meekness is set in opposition to pride and vain ostentation, and also to excessive zeal. To this he justly adds fear; for where reverence for God prevails, it tames all the ferocity of our minds, and it will especially cause us to speak calmly of God’s mysteries. For contentious disputes arise from this, because many think less honourably than they ought of the greatness of divine wisdom, and are carried away by profane audacity. If, then, we would render approved of God the confession of our faith, all boasting must be put aside, all contention must be relinquished.
Having a good conscience What we say without a corresponding life has but little weight; hence he joins to confession a good conscience. For we see that many are sufficiently ready with their tongue, and prate much, very freely, and yet with no fruit, because the life does not correspond. Besides, the integrity of conscience alone is that which gives us confidence in speaking as we ought; for they who prattle much about the gospel, and whose dissolute life is a proof of their impiety, not only make themselves objects of ridicule, but also expose the truth itself to the slanders of the ungodly. For why did he before bid us to be ready to defend the faith, should any one require from us a reason for it, except that it is our duty to vindicate the truth of God against those false suspicions which the ignorant entertain respecting it. But the defense of the tongue will avail but little, except the life corresponds with it.
He therefore says, that they may be ashamed, who blame your good conversation in Christ, and who speak against you as evil-doers; as though he had said, “If your adversaries have nothing to allege against you, except that you follow Christ, they will at length be ashamed of their malicious wickedness, or at least, your innocence will be sufficient to confute them.”
